Simultaneous Sensing of Dual Analyte Photonic Crystal Fiber Based Liquid Sensor

This article proposes three novel models of photonic crystal fiber insert ignore into journalissuearticles values(PCF); based dual liquid sensor. The performances of Z-Model, X-Model and V-Model structures have been evaluated by applying the well-known full vectorial finite element method insert ignore into journalissuearticles values(FV-FEM); where boundaries are defined with perfectly matched layers insert ignore into journalissuearticles values(PMLs);. The birefringence and the sensitivity levels of proposed sensors have been studied where core holes are filled with water insert ignore into journalissuearticles values(n=1.33); and ethanol insert ignore into journalissuearticles values(n= 1.354);. Our numerical results have shown that X-Model and Z-Model of A-Type sensor is an ideal structure for water and ethanol sensing, respectively.
